Jiang J, Wan R, Pan P, et al. - A retrospective study was conducted to compare clinical, laboratory, and radiological characteristics between COVID-19 and adenovirus pneumonia. Researchers conducted a retrospective observational study to examine and compared the clinical manifestations, laboratory findings, and radiological features of two independent cohorts of patients diagnosed with either COVID-19 (n=36) or adenovirus pneumonia (n=18). Many differences were observed between patients diagnosed with COVID-19 and those with adenovirus pneumonia in their clinical, laboratory, and radiological characteristics. The data indicated that COVID-19 patients tended to show a lower severity of illness in comparison with adenovirus pneumonia.
